I would have thought that if you are getting the onscreen console to follow what you are doing on the AR, you have the correct configuration. You should also find that pressing any of the first 10 registration memory buttons on the AR changes the stop settings on the Miditzer console.

The sound should only be audible through headphones or external speakers plugged into you PC, unless you have an audio cable from the headphone jack on the PC to the Aux Audio In (under the AR lower keyboard on the left) to make use of the AR's amp and speaker system. The Miditzer sound does not go back to the AR via the USB-midi cable.

I think maybe Charles has hit it on the head here when he says the control of the Miditzer from the AR 80 takes place through the midi-cable; but the sound does not go back to the AR via the USB-midi cable.

Charles ..

Do you have a cable from the Laptop's OUT (eg. the headphone socket) to the AR's LINE-IN (ie. the PHONO sockets under the AR) .. or into the Mic socket?

Terry ..

So how are you getting the sound back to the AR? Maybe you need to look at the Settings for the sound OUT from your Laptop. This would be done via the Sound Manager program on your Laptop. With my Laptop, just using Audacity was a nightmare as I have to configure Sound Manager to correctly allocate Inputs and Outputs. I have found in the end that it makes a difference which order I switch things on and plug them in. Recording to Audacity I have to first switch on my Mixer, plug the USB lead from that into my Laptop, and then turn my Laptop on. The Laptop is then searching for inputs and picks that up. If I don't already have the Mixer ON it picks up the INPUT internally from the Microphone on a headset, even though I don't even have a microphone on my headset. I just use headphones, but don't even have those plugged in. I think headset must be the 'default' if it can't find anything else, whether I am actually using headphones or not.

I mostly use headphones plugged into the PC when playing Miditzer through the AR. Sometimes I use an external amp and speakers with an audio cable from the PC headphone jack. Some years ago I did use the AR's amp and speakers by connecting an audio cable from the PC headphone jack to the AR AUX IN jack under the lower keyboard.

The order of doing things is important...

1. Plug in the USB-Midi cable at both ends2. Switch on the PC3. Switch on the AR and mute all AR voices4. Open Miditzer last

Do the reverse when finished playing though it is not necessary to remove the USB-Midi cable after switching off. In fact I leave my midi cables permanently plugged in the rear of the AR - too much trouble to keep moving the organ away from the wall. By the way, you can still play the AR at any time even if the PC is connected and Miditzer is not started.

You use the midi-cable to link the Miditzer program on a computer/laptop to the AR via the MIDI IN/OUT terminals (rear panel of the AR). Why the rear? What a pain! These two devices then 'talk to each other' so you can control the Miditzer's features via the AR.

The sound you hear emanates from the computer/laptop, so you need some device/amplifier to listen to it. Headphones plugged into the laptop is one way. But if you want to hear it all via the AR's amplifier, you need to take the sound output from the laptop (via the headphone socket) and put the other end into the AR's AUX IN jacks (RCA) .. ie. Phono sockets .. on the underside of the keyboard.

All this is covered in the Owner's Manual, page 159. There is also more on MIDI on page 162.

Below is an attachment of a document discussing Latency which is the time lapse between pressing a key and hearing the note.

This commonly occurs with pipe organs due to the distance between the pipes and the organ console. It takes time to produce the sound and for the sound to travel to the organist's ear.

Some users complain about the amount of latency in Miditzer while others are able to almost eliminate it. This document provides some ideas on things you can try if you are having difficulty playing with latency in the mix.

For those keenly interested in investigating Miditzer further, here is a link to the Miditzer Forum where I posted a more comprehensive document entitled “Playing Miditzer from the Yamaha AR80 (ver 2)”.

Playing Miditzer through the AR demonstrates yet again the versatility of the AR as a musical instrument through which you can enjoy the rich sounds of the mighty Wurlitzer organ in your own lounge room for just the cost of a USD-midi cable.
